Further, first lens section and second lens section are the semi-convex lens with straight flange, and the straight flange of two semi-convex lens is connected to each other together.
According to another aspect of the present invention, a kind of projector is provided, and has adopted following technical scheme:
A kind of projector comprises above-mentioned lens module.
Further; This projector also comprises the raw video generation module; Be used to generate raw video; Raw video comprises first image part and the second image part that is positioned at first image part top, and first raw video forms first image section through first lens section of projector in preset primary importance, and second raw video forms second image section through second lens section of projector in preset second position.
According to a further aspect of the invention, a kind of projector player method is provided, and has adopted following technical scheme:
Judge beholder's position; And
According to the beholder position, confirm first image part and the generation state of second image part of the raw video of projector, the image part of winning is divided and the second image part branch image projected is forward projection to the beholder.
Further, according to the beholder position, confirm that first image part of the raw video of projector comprises with second image generation state partly: when the beholder all is in projector's homonymy, keep the generation state of first image part and second image part.
Further,, confirm first image part and the generation state of second image part of the raw video of projector, comprising according to the beholder position: when the heteropleural of beholder in projector, about the first image part of upset after generating.
Compared with prior art, the invention has the beneficial effects as follows: according to the needs that difference is watched, raw video is cut apart, and passed through the eyeglass module of different focal, present different images and give corresponding beholder.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the eyeglass module imaging synoptic diagram of background technology of the present invention;
Fig. 2 is the structural representation of eyeglass module in the embodiment of the invention; And
Fig. 3 is the process flow diagram of the player method of projector in the embodiment of the invention.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
Fig. 2 is the structural representation of eyeglass module in the embodiment of the invention.
Referring to shown in Figure 2, a kind of eyeglass module that is used for projector is compared with existing eyeglass module, and improved part is, the eyeglass module is divided into first lens section and second lens section.Like Fig. 2, what be used for that the eyeglass module of projector comprises first lens section 203 and second lens section, 201, the first lens sections 203 and second lens section 201 is two and half different straight flange lens of focal length; And second lens section 201 is connected with first lens section 203, and the junction is a medium line.
Preferably, the curvature of first lens section 203 is greater than the curvature of second lens section 201.
Preferably, the refractive index of first lens section 203 is less than the refractive index of second lens section 201.
Through the technical scheme of present embodiment, can move raw video, let image partly through medium line, let different beholders see the image of demand separately.
The projector that comprises above-mentioned eyeglass module; This projector comprises raw video generation module (not shown); The raw video that generates is as shown in Figure 2, comprises that the first image part 205 and the second image part, 207, the first image parts 205 are connected with the second image part 207; Make institute of projector image projected be divided into first image section 209 and second image section 211; Wherein, first image section 209 projects preset primary importance, and second image section 211 projects preset second position.Can present different images according to different beholders like this, for example, for the speaker, not need large scale and imaging far away, the transparency that only needs to understand present report gets final product.So can utilize the less eyeglass of focal length to reach, the image that focal length is far away is seen to the audience, with near the seeing to the speaker of focal length.Above-mentioned improvement to eyeglass, curvature that can be through two set of contact lenses is different or let material (like the refractive index) difference of two groups of shape same lens, reaches the purpose of focal length difference.Need move the raw video that the raw video generation module generates simultaneously, let the image part all pass through medium line.And raw video comprises the first image part 205 and the second image part 207; First image section 209 that the first image part 205 is projected is left spectators for; Second image section 211 that the second image part 207 is projected is left the speaker for; Speaker's information also can be put into wherein, the picture of for example reminding the spectators such as timer of speaker's time can not need to see.
Fig. 3 is the process flow diagram of the player method of projector in the embodiment of the invention.
Referring to shown in Figure 3, the player method of above-mentioned projector comprises:
S1: the position of judging the beholder; And
S2: according to the beholder position, confirm the generation state of first image part and second image part of projector, the image part of winning is divided and the second image part branch image projected is forward projection to the beholder.
For different application scenarios; Adjustment need be made to first image part of raw video and the generation state of second image part by above-mentioned projector; Promptly need make judgement to beholder's position; If the beholder is in the same side of this projector, keep first image part and second image generation state partly so.
If the beholder is in the both sides of this projector respectively; To make adjustment to the generation state of first image part so; About the first image part of upset after generating, this image is a forward projection for the beholder of the second image part image projected like this.
Therefore, can find that the needs that technical scheme of the present invention can be watched according to difference will be through moving raw video, and the eyeglass module through different focal, present different images and give and watch colony accordingly.
Be merely the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
